Hello, i,m not computer savvy to be honest. I bought a cheap dac to use with laptop in my workshop. As usual with me, plugging it in to usb and headphones was too easy to work straight away. My research says laptop needs a different driver possibly? The dac is working in as much the power light is on when plugged into usb, and when headphones are in other end, you get the impression [slight interference] through headphones that its probably not a faulty unit. When music is played only sound comes from laptop. The dac is a Techole HS202. Any help is appreciated
